Q: What is leukoplakia?
A: Leukoplakia is characterized by a thick, white patch of excess cells growing inside the mouth on the tongue, cheek, or gums. Although leukoplakia can be caused by oral irritation due to badly fitted dentures or a sharp tooth edge, it is a very common side effect of tobacco use. Leukoplakia carries a risk of developing into cancer. Your dentist can help monitor the leukoplakia and perform tests if problems arise.
